Problems with catkin_make after installing from source

edit

Hi, I've been trying to fix errors that occur when using the gym_gazebo package, and the solution to one of my problems was to uninstall gazebo and install it from source, and I followed the instructions that are contained here, however now when I try to run catkin_make, i get the following message. Did I make a mistake during the installation?
